Kookaburras coach Colin Batch said: “We always viewed the start of the FIH Pro League was about finding out about our players and their form.

“We’re still going with that. We had six changes from the team for Melbourne to Hobart. We had a group back here training who had a good training week and a lot of them come back.”

Batch confirmed Margaret River’s Aran Zalewski would be the sole captain in his home state for the first time since officially joining Eddie Ockenden as the team’s co-captains.

“Aran will lead us in Perth,” Batch said. “It makes sense for him to lead us in his home city as Eddie did in Hobart last weekend.

“He’s joined by Tom Wickham, Jake Harvie and Trent Mitton as the four local boys.”

The Hockeyroos have been forced into two changes with Jodie Kenny and Madison Fitzpatrick unavailable due to injury.

Georgina Morgan returns for the first time since being appointed co-captain. She’s joined in the 18-member team by Jocelyn Bartram, Kalindi Commerford and WA’s Penny Squibb.

Along with Kenny and Fitzpatrick, Kristina Bates, Hayley Padget and Ashlee Wells make way.

Hockeyroos coach Paul Gaudoin said: “It’s pleasing to see Georgina Morgan back in after injury as one of our co-captains. We’re looking forward to seeing her perform this weekend.

“With the injuries to Jodie and Madison in defence, Penny Squibb has also warranted selection which is pleasing for her as a local player.”

Gaudoin said the selectors had been cautious on Kenny who missed both of last weekend’s matches in Hobart after picking up the quad injury in training.

“Jodie was close with her quad injury but we wanted to be cautious,” Gaudoin said.

“Madison rolled her ankle and we’re hoping she’ll be on the mend for the coming weeks.”
